| 1. RELIABILITY | |
| A. Internal Consistency | Tested |
| Cronbach's (Describe) |
Cronbach's alpha= 0.940 |
| B. Reliability intraobserver or test-retest | Tested |
| Continuous scores: intraclass correlation coefficient (ICC) Dichotomus: Cohen kappa (Describe) |
Intrarater reliability of CollaboRATE mean scores was demonstrated for both response scales, with excellent intraclass correlations observed between Time 1, initial survey completion, and Time 2, resurvey, scores (ICC reached 0.90). Intrarater reliability of CollaboRATE top scores was also demonstrated for both response scales, with moderate agreement observed between Time 1 and Time 2 scores (kappa=0.58). |
| C. Reliability interobserver or Measurement error | Not Tested |
| Standard error of measurement (SEM), smallest detectable change (SDC) or Limits of agreement (LoA) (Describe) |
|
| 2. VALIDITY | |
| A. Content validity: face validity | Not Tested |
| Expert opinion (relevance and comprehensiveness) (Describe) |
|
| B. Construct Validity: Structural validity |
Not Tested |
| Hypotheses-testing | Tested |
| Cross-cultural validity | Not Tested |
| Brief Description | |
| C. Criterion validity | Tested |
| Comparison with a 'gold standard' Continuous scores: correlations, ROC curves Dichotomus: Sensitivity & Specificity (Describe) |
The concurrent validity of CollaboRATE was demonstrated with moderate to strong positive correlations between 2 other measures of SDM for both response scales and both scoring methods. |
